Steps to Calculate GCD of 385, 361, 221, 170 using LCM Formula

Given numbers are 385, 361, 221, 170

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(385, 361) = 138985

GCD(385, 361) = ( 385 x 361 ) / 138985

= 385 / 361

= 385


Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1


Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1


So, Greatest Common Divisor of 385, 361, 221, 170 is 1
